# list_creative_formats

Discover creative formats supported by a sales agent. Returns formats used by active products with references to authoritative creative agents.

For complete API documentation with request parameters, response structure, and testable examples, see the [list\_creative\_formats Task Reference](/dist/docs/2.5.3/creative/task-reference/list_creative_formats).

## Sales Agent Behavior

Sales agents implement `list_creative_formats` differently from creative agents:

**Sales agents** (like `https://test-agent.adcontextprotocol.org`):

* Return **only formats used by active products**
* Reference creative agents for authoritative format specifications
* Filter results based on what's actually purchasable

**Creative agents** (like `https://creative.adcontextprotocol.org`):

* Return **authoritative format definitions** they own
* Provide full specifications for building and validating creatives

## Response Structure

Sales agent responses include:

```json theme={null}
{
  "formats": [
    {
      "format_id": {
        "agent_url": "https://creative.adcontextprotocol.org",
        "id": "display_300x250"
      },
      "name": "Display 300x250",
      "type": "display"
    }
  ],
  "creative_agents": [{
    "agent_url": "https://creative.adcontextprotocol.org",
    "agent_name": "AdCP Reference Creative Agent",
    "capabilities": ["validation", "assembly", "preview"]
  }]
}
```

**Key differences from creative agents:**

* Formats may reference external creative agents via `format_id.agent_url`
* `creative_agents` array provides entry points for full format specs
* Format list is filtered to purchasable inventory

## Typical Workflow

1. Call sales agent's `list_creative_formats` to see available formats
2. For full specs, query the creative agent at `format_id.agent_url`
3. Use format specs to build and validate creatives
